Old continent pagan converted by Hare Krishna at last (7)
I believe the answer is:
pangaea
'old continent' is the definition.
'pangaea' can be an answer for 'continent' (Pangaea is an example). I am unsure of the 'old' bit.
'pagan converted by hare krishna at last' is the wordplay.
'converted' indicates an anagram.
'by' says to put letters next to each other.
'at last' indicates one should take the final letters.
The final letters of 'hare krishna' are 'ea'.
'pagan' is an anagram of 'panga'.
'panga'+'ea'='PANGAEA'
Can you help me to learn more?
(Other definitions for pangaea that I've seen before include "Original large continent" , "land now broken up" , "Original supercontinent" , "Hypothetical early continent, all earth in Greek" , "ancient landmass" .)
